Marshall 攻擊(Marshall attack, Marshall counter-gambit)(1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O 8.c3 d5) 係國際象棋嘅西班牙開局(en:Ruy Lopez)入面嘅一種開局系統,黑棋響e5送一隻兵畀對手,換來局面空間同發展時間。

Marshall 攻擊本來係種對付西班牙開局嘅武器,但近幾十年因開局理論發展,已經被研究得好深,好易成和。 而且白棋可用一啲方法,好似改下行棋嘅次序,來避開佢 (即係所謂「反 Marshall 系統」(en:anti-Marshall system))。
